[PVE-User] Request for backport of Ceph bugfix from 12.2.9

[Uwe Sauter]

Hi,

I'm trying to manually migrate VM images with snapshots from pool "vms" to pool "vdisks" but it fails:

# rbd export --export-format 2 vms/vm-102-disk-2 - | rbd import --export-format 2 - vdisks/vm-102-disk-2
rbd: import header failed.
rbd: import failed: (22) Invalid argument
Exporting image: 0% complete...failed.
rbd: export error: (32) Broken pipe

This is a bug in 12.2.8 [1] and has been fixed in this PR [2].

Would it be possible to get this backported as it is not recommended to upgrade to 12.2.9?


Regards,

Uwe

Possible yes, but it looks like that the Ceph version 12.2.10 may be
soon released, including this fix.

For now I would wait with backporting, as we would need to test a
backported 12.2.8 as well as we will with a new 12.2.10.

This is a minimal proposed change which looks just right, so much testing
may not be needed, i.e., just the change part once - at least if it
applies cleanly.

But as a ceph rollout is quite a bit of work besides that I agree with
Alwin that it probably makes sense to wait at the soon arriving 12.2.10

cheers,

Hi all,

thanks for looking into this.

With help from the ceph-users list I was able to migrate my images.

So no need anymore.

Best,

Uwe
